In the search for alternatives to traditional paint systems solvent-based, the curing process of polymer coatings by ultraviolet light (UV) has been widely studied and discussed, especially because of their high content of solids and null emission of VOC. In UV-curing technology, organic solvents are replaced by reactive diluents, such as monomers. This paper aims to investigate variations on color, gloss and hardness of print inks cured by different UV radiation doses. The ratio pigment/clear coating was kept constant. The clear coating presented higher average values for König hardness than pigmented ones, indicating that UV-light absorption has been reduced by the presence of pigments. Besides, they have indicated a slight variation in function of cure degree for the studied radiation doses range. The gloss loss related to UV light exposition allows inferring that some degradation occurred at the surface of print ink films. 相似文献

Plastics have been used in short-life products, which have presented harmful consequences for the nature, because of the low
degradation rate reached by the most common polyolefins. This work evaluates the mechanical and thermal properties of pure
iPP, plasticized starch (TPS) with biodiesel (TPSBio) or commercial (TPSCom) glycerols, and their blends (iPP/TPSPlas). The addition of TPSPlas caused an increasing on the cristallinity of iPP, mainly for the compositions 90/10 and 80/20, probably due to morphological
alterations such as crosslinking, that may have modified the molecular arrangement of the iPP in the presence of glycerol. 相似文献
